How to Make Chewy Peanut Butter Butterfinger Cookies
Step 1: Prepare the Oven and Baking Sheet
Start by preheating your oven to 350°F so it’s ready as soon as your dough is mixed. Line a large baking sheet with parchment paper—this prevents sticking and encourages even browning for that perfect cookie texture.
Step 2: Cream the Butters and Sugars
In a large mixing bowl, beat together the softened unsalted butter, creamy peanut butter, granulated sugar, and packed light brown sugar. Mix until it’s light and fluffy, about 2–3 minutes. This step is all about building air into the dough for a soft, chewy bite and setting a dreamy peanut butter base.
Step 3: Add the Egg and Vanilla
Crack in your egg and pour in the vanilla extract. Stir until everything is thoroughly combined. The egg helps hold the cookies together and adds richness, while the vanilla brings out all the nuanced flavors you crave in these Chewy Peanut Butter Butterfinger Cookies.
Step 4: Combine the Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add this dry mixture to your wet ingredients, stirring just until a soft dough forms. Don’t overmix—it’s the secret to keeping your cookies melt-in-your-mouth tender!
Step 5: Fold in Butterfinger Pieces
Add the chopped Butterfinger candy bars and gently fold them into the dough. Every generous scoop ensures plenty of chewy peanut butter cookie with those classic Butterfinger nuggets in every bite.
Step 6: Portion and Bake
Use a heaping tablespoon (or cookie scoop) to portion dough onto your prepared baking sheet, spacing each ball about 2 inches apart. Bake for 10–12 minutes, just until the edges are golden and the middles are set but still soft—this is the key to achieving ultimate chewiness! Let them cool for 5 minutes on the pan, then transfer to a wire rack to cool completely. The scent alone will make it nearly impossible to wait!
How to Serve Chewy Peanut Butter Butterfinger Cookies

Garnishes
For a special finishing touch, sprinkle extra chopped Butterfinger pieces on top of each cookie right after baking, while they’re still warm. You can also drizzle with a little melted chocolate or even a dusting of flaky sea salt to elevate the sweet-salty flavor. These little details add a bakery-worthy flourish and a bit of extra crunch in every bite.
Side Dishes
Pair your Chewy Peanut Butter Butterfinger Cookies with tall glasses of cold milk or creamy vanilla milkshakes for the ultimate nostalgic treat. For grown-up gatherings, try serving them alongside a cup of robust espresso or a scoop of peanut butter ice cream to double down on those rich, nutty flavors.
Creative Ways to Present
Arrange your cookies in a tall stack tied with twine for a perfect homemade gift, fill a festive cookie tin for holidays, or even sandwich a scoop of ice cream between two Chewy Peanut Butter Butterfinger Cookies for an unbeatable dessert. Kids and adults alike can’t resist turning these into cookie sundaes or party favors!
Make Ahead and Storage
Storing Leftovers
After your cookies have cooled, store them in an airtight container at room temperature for up to five days. If you layer the cookies, separate them with a sheet of parchment paper to keep the Butterfinger pieces crisp and the cookies soft and chewy for days.
Freezing
For ultimate convenience, shape the dough into balls and freeze them unbaked on a tray. Once solid, transfer them to a freezer-safe bag. Bake straight from frozen, adding 1–2 extra minutes to the baking time. You can also freeze baked cookies, well-wrapped, for up to 2 months and thaw as needed for an instant treat.
Reheating
If you’re craving that just-baked warmth, pop a cookie in the microwave for 10–12 seconds. This softens the cookie, slightly melts the Butterfinger bits, and brings the magic right back—even days later!
FAQs
Can I use chunky peanut butter instead of creamy?
Yes, you can swap in chunky peanut butter for an extra crunch. Just keep in mind, the texture of your Chewy Peanut Butter Butterfinger Cookies will be a bit more rustic, but still deliciously chewy and full of nutty bites.
How finely should I chop the Butterfinger bars?
Chop the Butterfinger bars into small, bite-sized chunks, about the size of a chocolate chip. This way, every bite of your Chewy Peanut Butter Butterfinger Cookies has plenty of crispy, candy-packed goodness without overpowering the cookie.
Can I make these cookies gluten-free?
Absolutely! Substitute a good quality 1:1 gluten free baking flour for the all-purpose flour. The results may be just a touch softer, but the peanut butter and Butterfinger flavors will shine right through.
Can I double the recipe?
Of course! Simply double all the ingredients. You may want to bake in batches or use two baking sheets so the cookies have space to spread and bake up perfectly chewy every time.
What should I do if I can’t find Butterfinger bars?
If Butterfinger bars aren’t available, you can substitute with any crispy, peanutty candy bar, or even try toffee bits for a similar experience. The cookies will be slightly different, but still delicious and loaded with sweet crunch.
